filesystem-context-mcp-server
Verified Safeby j0hanz
Overview
Provides AI assistants with secure read-only filesystem access for exploring, searching, and reading files within approved directories.
Installation
npx -y @j0hanz/fs-context-mcp@latest --allow-cwdSecurity Notes
The server implements robust security measures including explicit read-only operations, comprehensive path validation to prevent traversal and symlink escapes, RE2-based regex engine to prevent ReDoS attacks, and configurable resource limits. A dedicated test (`filesystem-boundary.test.ts`) enforces strict boundaries for `node:fs` imports, indicating a strong security-first architectural approach. No 'eval', obfuscation, or hardcoded secrets were found. Uses stdio for communication, reducing external network attack surface.
